What is the solution of this system of linear equations? 3y = 3 y equals StartFraction 3 over 2 EndFraction x plus 6.X + 6 y – S

Scrat [10]

Answer:

(0,6)

Step-by-step explanation:

The given system of equations is

$y = \frac{3}{2}x + 6$

and

$\frac{1}{2}y - \frac{1}{4}x = 3$

We substitute the first equation into the second equation to get:

$\frac{1}{2} ( \frac{3}{2}x + 6) - \frac{1}{4}x = 3$

We expand to get:

$\frac{3}{4} x + 3 - \frac{1}{4}x = 3$

We group similar terms to get:

$\frac{3}{4}x - \frac{1}{4}x = 3 - 3$

$\frac{1}{2}x = 0$

$x = 0$

Put x=0 in to the first equation to get:

$y = 6$

Therefore the solution is (0,6)
